Space Brain Circuits DarkSky-4 | Stereophonic Analog Polysynth

video upload by Space Brain Circuits

"All sounds are directly from DarkSky-4 without any external effects or plugins.

User manual:"

New synth priced at $699.00, from the maker of MidiVolts.

"DarkSky-4 is a 4 voice stereophonic analog synthesizer.The synthesizer consists of 4 independent oscillators that can be played monophonically, paraphonically or polyphonically. Each oscillator is equipped with a dedicated VCA and Envelope, which allows for better musicality and the ability to sound each note as it is pressed. Each oscillator contains a sawtooth and square wave, which can be mixed to generate various timbres and sounds. The square waveform can be gradually adjusted from a square waveform to a narrow pulse width waveform to further expand the sonic characteristics of the oscillators. The synthesizer also features two 24dB low pass filters with dedicated controls for cutoff frequency and resonance peak. DarkSky-4 provides several ways to add modulation to the audio signal, including frequency modulation, pulse width modulation, and filter modulation. The unit was designed to create a more expansive soundscape for studio and performance settings. The filter adjustments, along with filter modulation, provide a wide range of stereo effects when in stereo mode. Additionally, the semi-modular patch bay can be used to further modulate multiple sources of controls."

Crumar Bit 01 demo with midi controller

video upload by ohm_studi_ohm

"Here is a demo of this italian 6 voice analog polysynth i'm selling (
Unit was upgraded with the great Tauntek firmware and can now be controlled remotely over midi by Control Change with any controller.
In the demo I basically flip through the unit presets and edit some of them on the fly just to show how easy it is now to program this otherwise austere synth.

I didn't demo the bi-timbral feature of the rack. You can have 2 different presets, lower and upper, either layered ("double") or split. Lower and Upper parts can have their own audio output.
Preset from 76 to 99 are allocated for the performance presets and need to be dialed in (you can't use the + and - value switch to select those like I did on the video)."

SN 00522 via this auction

"Italian 6 voice analog polysynth. This is the CEM 3328 version, not the SSM 2044 one, in the rare white colour.

This unit was serviced and upgraded and is in perfect working condition, see video.
What was done:
- power supply capacitors were replaced
- new battery was installed
- Tauntek new firmware eproms were installed. You can now control the unit directly over MIDI with CC with any hardware or software controller
- Midi thru socket was modified so that you can export your preset by sysex dump over midi (original could only export presets through the "tape" function)

It also comes with some goodies (well especially for french speaking person)
- original owner's manual + preset lists (in french)
- original schematics diagram
- original Crumar Bit range advertissement (in french)
- original inspection card from factory (this unit came out from factory in November 1985)

Condition is very good with only minor scuffs to the nice white metal paint."

Stand by Me: The Sounds Made for the Film

video upload by

"In this video, Anthony tells the story surrounding the musical score from (1986) hit film Stand by Me which features an All-Star cast that incudes River Phoenix, Wil Wheaton, Corey Feldman, Jerry O'Connell, Kiefer Sutherland, Casey Siemaszko, John Cusack and Richard Dreyfuss.

We learn that the first version of the film was titled The Body, named after the novel by Stephen King. The film's director, Rob Reiner intuitively changed the film's name to Stand by Me after licensing the rights to the song with the same name written by Ben E. King along with Jerry Leiber and Mike Stoller. The name change was made only one week before the film's delivery date. With little time to spare, the musical score was re-created using the sounds and melody from the song and performed on the Synclavier Digital Music System using it's on board sequencer/recorder and employing a sound modeling technique unique to the Synclavier called "Resynthesis".

Anthony describes "Resynthesis"as creating synthesizer sounds based on samples analyzed by the computer that use cross fades of back-to-back wave tables. "Resynthesis" gives you the tonal character of the original sampled sound with all the benefits of a synth (e.g less memory, same length across the keyboard, more editing capabilities...) Along with Brian Banks, Anthony programmed all the sounds and replayed the entire score in this way after the original score by Oscar Winning composer Jack M. Nietzsche was abandoned. The film's director Rob Reiner was present throughout the scoring process. The duo had just completed work programming and performing Jack's score for the John Carpenter Oscar Nominated film Starman.

In this video you'll hear the actual sounds used in the film that Anthony loads from the original 5.25" floppy disks (that still work perfectly after being in storage for close to 40 years). The final score used a core instrumentation of resynthesized versions of a flute, stand up bass, bowed wine glasses and piano. There was no DAW in existence so all the tracks were input into the Synclavier's internal sequencer/recorder and locked to picture using the latest feature SMPTE time code. With this set up, everyone could watch the film while the music was being recorded.

Anthony also states the importance of a good film or a good song. It's all the difference in the potential of your work as a programmer, arranger or performer. He advises to step back and really listen to what you are creating to find the emotion in the sounds.

Anthony's musical touch as both composer and performer is connected with some of the most influential creative minds over the last 40 years. He’s composed and conducted original orchestral scores for over 80 feature films including Young Guns, Internal Affairs, The Man From Elysian Fields, 15 Minutes and Planes, Trains & Automobiles, been commissioned by the Los Angeles Philharmonic for his symphonic work "In the Family Way", written over one thousand TV commercials in a myriad of musical styles, co-founded Levels Audio Post (LA's premiere post production facility) and performed and arranged on big-box-office films and influential hit records such as Michael Jackson's Thriller.

His extensive work as a young arranger, orchestrator and performer for Quincy Jones, Jack Nitzsche, Lamont Dozier, Arthur Rubenstein and Giorgio Moroder was vital in launching his own career. His early years pioneering modular analog synthesizers along with his wide-ranging music scholarship positioned Anthony at the center of the music technology revolution. He attended the University of Southern California School of Music as a piano and composition major.

Philicorda GM 751 Valve Organ from 1967

video upload by Vintage Keys Studio

"Steve Christie from Vintage Keys Studio demonstrates a fully working* Stereo Philips Philicorda GM 751 Organ in all its glory.

This organ came to our studio in need of repair and has been fully restored by Steve. It is a valve/transistor hybrid from 1967. Later models were solid state.

Comes with a LDR based swell pedal which attaches to the base of the organ via a DIN plug. It has two internal speakers that face out left (source signal) and out right (source signal / reverb switched) for a stereo effect.

The organ is mounted on a sturdy iron frame with attractive wooden supports, and comes with its own equally attractive music stand.

Valves: 8 x ECC83, 1 x ECL82,
Neon Lamps/Diodes: 5 x Z70U, 68 x ZA1001, 1 x ZZ1000
Transistors: 3 x AC125, 2 x AC128, 4 x AD149

This organ has been used in sessions for many years and continues to remain a reliable keyboard with a wonderful variety of sounds which can be modified using the 5 filters and their combinations, 3 organ registers, Vibrato circuit and Reverb (called 'Reverbeo') - on German models this is labelled 'Hall'

Steve and other session musicians from Vintage Keys are available to record this organ for you as a layer to add to your own project. Please contact us at for more details."

Don't think of it as a classic delay and even as a BBD delay it's still very unique because DELAY 1 has none of the whine but ten times the amount of inputs, outputs and knobs to tweak. It can be used to waveshape and combfilter, to create (stereo) chorus and flanger. It can be used as a voice by itself (with immaculate tracking) or as an all in one noise bass drone synth."
